Patented Dec. 17, 1929 UNITED STATES PATENT; 1 ounce ESMOND F; WILEY, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO UNIVERSAL WIN- DOW COMPANY, OF OAKLAND, CALIFORNIA, A CORPORATION OF CALIFC-"RNIA LATCH FOR AWNl'NG'r-TYPE WTNDOWS Application filed January a1, 1922. Serial m aoyra This invention relates to hardware and particularly pertains to a sash latch for awning .maintaining the latch bolt latched to the strike plate on the frame when the window is closed.

One form which the invention may assume is exemplified 1n the following description and illustrated by way of example in the accompanying drawings, in which Fig. 1 is a view of the latch in. latching position.

Fig. 2 is a view of the latch with the win dow partially open and with parts of the mechanism in section. j r

Fig. 3 is a view of the latch just released. Fig. 1 is a fragmentary view showing a portion of the interior surface of the sash and the stool with my improved latch mechanism connected therewith and arranged in latched position. 7 Z 7 Referring more particularly to the accompanying drawings, 10 indicates a sash of an awning type window and 11 thelower rail thereof. This sash is adapted to cooperate with a sash frame 12 including a sill 14; and a stool 15. Secured to the inner face of the lower rail 11 of the sash is a bracket 16. This bracket comprises a foot plate 17 whichmay be screwed or otherwise secured to the rail 11. Extending from this toot plate lZis a channeled. extension 18, the sides of which are parallel and spaced apart.

Arranged between the sides'ot the QXlZO11- sion 18 is a latch bolt 19 which is pivoted 011 the extension 18. Also pivotally mounted between the sides of the'extension 18 is a handle 21. This handle 21 is pivoted at its inner end between the outer ends of the sides of the extension 18 on a pivot pin 22. At its outer end the handle 21 is provided with a grip portion 23. It is intended that this handle 21 be utilized bothto operate the sash 10 and to I maintain the latch bolt 19 in latched position bolt 19 to latch the sash 10 in closed position.

he latch bolt 19 has a second projection 27which is adapted when engaging the lug 25 on the strike plate 24 to throw the projection 26 downwardly so that it will engage the inner side of the lug 25 on the strike plate, and thereby place the latch bolt 19 in latched position as shown in Fig. 3. I

The latch bolt 19 is normally maintained in a non-latching position by a spring 28 interposedbetween the latch boltand the top portion of the extension 18. The position of this spring issuch that the latch bolt 19 will be normally yieldablyheld in a position with its projection 26 in a raised or non-engaging position. While in the present instance, I

have shown a spring to accomplish this object, it is obvious that the latch bolt 19 may be so balanced about its pivotal. point that this effect may be obtained without the necessity of providing a spring. That is to say, the end of the latch bolt opposite the projection 26 may be weighted so as to normally maintain the opposite end elevated.

To secure thelatch bolt19 in engagement with the keeper lug .25 onthe strike plate 24, the handle 21 is provided with a cam surface 29 about its pivotal point 22. This cam surtace'29 is'eccentric to the pivotal point of the handle and is adapted to engage the contiguous end of thelatch bolt 19 and to secure the latter in latching position as shown in 1. In Fig. 2, the handle is shown extended substantially horizontally and inwardly of the window while in Fig. 1 with the latch in latching position, the handle is swung downwardly to the vertical, so that it type window andthestrike plate-24% secured does not project much beyond the end of the extension 18 of the bracket.

'In operation of the device, it is constructed and assembled as illustrated in the drawings, and the latch mechanism is secured to the lower ra1l=of-the sash ofi-an awningiorl swingmg on the stool oi the sash frame.

1 VVhemdesiring to open the window, the

handle is disposed asshown in Fig. 3 and pushed outwardly to open the window. This outward movement of the window will'zcause.

the projection 26 on the latch bolt 19 to ride over the lug 25 on the'strike platefl and to 7 place the end 30 of the latch bolt .19 into en- "gagement *with'a notch 31' on *the inner end of the handle'21, sothatthehandl'e will'dfi'er afirm hand hold whenthei windowis pushed outwardly.

'When closingthewindowa pullis'exer'ted on the handle-'21 to draw the windowinward l-yinto positionin its 'frame. As the window' swings inwardly, the projection '26 on the latch bolt 19 will clear the lug on the strike plate buttheprojection 27 will strike its cam surface 29 will cngage'the'toprofthe end "30 0f the-latch"bole-19, and firmlysecure the projection 26 on the l'lath: bolt 19 in en j gagement with the inner side of the-lug 25 on the strike plate 24. Intliis" positionflthe handle 21 will bedisposed in an t1nobstructing position as disclosed-Fin Figfilyand will not "in any way interfere with the'use er in side screens or shutters' =on'=the windows.

From the foregoing "it ist =obvious= that I l have provided-*aneat appearing inexpensive window latch of simple construction and whic'hwi'll operate e'ificiently to l atcha swing-- ing" type window in closed position.

defined in the appended claims.
